Question

In a study of the invasive species heracleum

mantegazzium,

Jan Pergl and associates compared the density of these plants in their native area in Russia and in an invaded area of the Czech Republic.

In their native area, the average density was well-established as

= 5 plants per square meter. In an invaded area, a sample of n = 60 plants produced an average density of x = 11.117 plants per square meter with a sample standard deviation of s = 2.37 plants per square meter.

Using a signficance level of

= 0.01, is there sufficient evidence to conclude that the density of the species in the invasive area is significantly higher than in the native area?

Use the hypothesis-testing framework to answer this question. Be sure to state both the null and alternative hypothesis, calculate a test statistic, and state the conclusion in non-technical terms. You may use either the P-value or critical value method, but make sure to state which method you use.
